Failed to load resource: net::ERR_INSUFFICIENT_RESOURCES when creating Infinite Scroll
In my front page, I made it for the webpage to load more results when the user scrolls to the bottom of the page. It's paginated so that it loads 15 results at a time. When I'm testing, I have almost 400 in total, and it shows Failed to load resource: net::ERR_INSUFFICIENT_RESOURCES at about 9th page and the page kind of freezes. Why does this happen even though I'm only loading 15 at a time? Do you think I have to use multiple webpage pagination (the "ordinary" pagination where you get redirected to next page)? By the way, I use pure javascript for front-end, and django rest framework in the back-end. I'm kind of a beginner, so my explanation might not be clear, so please be patient with me. -
How to update field and not refresh the template
I am making the polls app in the first Django tutorial. I see each time you vote, the page refresh and goes to the top of the page, I want it to just stay where it is and only update the paragraph tag. detail.html: <html dir="rtl"> <h1>{{ article.title }}</h1> <h2>{{ article.author }}</h2> <h1>{{ article.text }}</h1> <p>I have {{article.votes}}</p> {% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %} <form action="{% url 'main:vote' article.id %}" method="post"> {% csrf_token %} <input type="submit" value="Vote"> </form> </html> vote function in views.py: def vote(request, article_id): article = get_object_or_404(Article, pk=article_id) article.votes += 1 article.save() # TODO: Change it so it doesnt return new refreshed html return render(request, 'main/detail.html', {'article': article}) -
Inconsistent MEDIA URLs in Django 3.0 vs 3.1 in tests
I have a Django project whose models have a thumbnail image, and I have some tests to check the generated paths of the images. # myapp/models.py from django.db import models def thumbnail_upload_path(instance, filename): # There's more happening in this method, but to simplify: return f"books/{filename}" class Book(models.Model): thumbnail = models.ImageField( upload_to=thumbnail_upload_path, null=False, blank=True, default="" ) # tests/myapp/test_models.py from django.test import TestCase from myapp.factories import BookFactory # using factoryboy class BookTestCase(TestCase): def test_thumbnail_url(self): book = BookFactory(thumbnail__filename="tester.jpg") self.assertTrue(book.thumbnail.url.startswith("books/tester")) That test passes in Django 2.2 and 3.0. But when running it in Django 3.1 the thumbnail URL starts with a slash: "/books/tester..." I'm guessing it's this change in 3.1... The STATIC_URL and MEDIA_URL settings set to relative paths are now prefixed by the server-provided value of SCRIPT_NAME (or / if not set). This change should not affect settings set to valid URLs or absolute paths. I'm not sure how to make the test behaviour consistent in all Django versions. When running the tests I set MEDIA_ROOT to tempfile.mkdtemp(). I've tried appending a "/" to the end of that. I've tried setting FORCE_SCRIPT_NAME to "/". On the actual website - not in the tests - I have MEDIA_ROOT = "/" and the image paths … -
Showing Anonymous user error and also not able to check whether user is authenticated only on one page.Working fine on all others in django
My views.py was working fine for every function except the below one(handlerequest).It is showing me error that Anonymous user has no object customer on website even when there is (working correctly on other pages).

Django: No route found for path 'messages/'
So I have a django project that includes websockets, it works perfect, then I decided to add to another html file script the websockets code to have in two pages the same websockets, the problem is that the websockets of the second page is giving me this error No route found for path 'messages/'. What I think the problem is that I did not add the other url page "messages" to my routing. does anyone know what is going on? -

Django KeyError on handling of JS cookies
I am doing some simple web-shop project in django and keep having this issue after cleaning cookies generated and running project. KeyError at / 'device' I've already understood that code generating the problem is from one of views files (the line of most importance here is device = request.COOKIES['device'] ): def cartData(request): if request.user.is_authenticated: customer = request.user.customer else: device = request.COOKIES['device'] customer, created = Customer.objects.get_or_create(device=device, name = None) order, created = Order.objects.get_or_create(customer=customer, complete=False,) items = order.orderitem_set.all() cartItems = order.get_cart_items return {'cartItems':cartItems ,'order':order, 'items':items} I need a system that creates a device code that allows me to track people without authentication.

Django: Why does a POST to UpdateView silently fail?
I've had a couple of occasions where I have introduced a very annoying bug into my Django site. I'm using Class Based Views (CBV), and I caused CreateView and UpdateView to silently fail. The repro steps for, say, the CreateView problem are: Enter a URL into the browser to display the CreateView-related form Enter the form data Click the submit button The completed form re-appears but no object is created - Django doesn't go to the URL in the model's get_absolute_url(...) function # views.py snippet class ListingUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView): model = Listing fields = ['orig', 'dest', 'container_type_code', 'container_bic_owner', 'container_max_kg', 'ship_imo', 'ship_owner_imo', 'ship_embarkation', 'ship_sailing', 'ship_docking', 'ship_unloaded', 'reserve_price', 'buy_now_price', 'currency', 'stage'] # listing_form.html snippet <div class="col-4" style="padding-left: 0; display: inline; float: left;"> {{ form.orig|as_crispy_field }} </div> <div class="col-4" style=" display: inline; float: left;"> {{ form.dest|as_crispy_field }} </div> <div class="col-4" style=" display: inline; float: left;"> {{ form.container_type_code|as_crispy_field }} </div> As you can see, I render individual fields rather than render the whole form with one tag. -
Django "OR" like statement in Queryset?
Just have a simple syntax question onto Django, imagining the following queryset: queryset = Requests.objects.get_queryset().filter(status='Pending', up_rank__gte=config.REQ_RANK - 10, down_rank__gte=config.REQ_RANK - 10) Is there any way that I can setup my query like that: up_vote__gte=config.REQ_RANK - 10 OR down_vote__gte=config.REQ_RANK - 10 ?! (See pseudo OR) As I want to filter onto both, up_rank and down_rank __gte. The only way I know would be a query chain but to me that seems not to be efficient, Is there any other way than a query chain statement or do I just talk nonsense and chain is fine? Thanks in advance -

User registration using UserCreationForm failing to save to database
I've been learning Django and I'm trying to understand how to extend some of the built-in functionality. To do that I've referenced Customizing Authentication in Django and tried to implement the instructions I've found there in a standard django-admin project. The problem is that when I try to save the form to the database (sqlite3 included db), nothing is recorded. The form passes the is_valid check, but when I check the database however, nothing has been added to either my user or patients tables. Hoping someone can point out where this is going wrong, thank you. models.py from django.db import models from django.contrib.auth.models import AbstractUser class User(AbstractUser): isPatient = models.BooleanField(default=False) class Patient(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) age = models.PositiveIntegerField() forms.py from django import forms from django.contrib.auth.forms import UserCreationForm from django.db import transaction from .models import * class RegisterPatient(UserCreationForm): age = forms.IntegerField() class Meta: model = User fields = UserCreationForm.Meta.fields + ("age") @transaction.atomic def save(self, commit=True): user = super(RegisterPatient, self).save(commit=False) user.isPatient = True user.save() patient = Patient.objects.create(user=user) patient.firstName.add(*self.cleaned_data.get('age')) patient.save() views.py def register(response): form = RegisterPatient(response.POST) if form.is_valid(): print("is Valid") # < Code reaches here form.save return redirect("/") settings.py AUTH_USER_MODEL = 'main.User' admin.py from django.contrib import admin from django.contrib.auth.admin import UserAdmin … -
rollback saved objects whenever email send failed
Hi I've been wondering how to rollback a saved object on a following method when one method failed. forms.py # somewhere class forms def handle(self, view, request, *args, **kwargs): # assuming i get an object successfully. application = models.Application.objects.first() # do something in its attrs and save application.name = 'test' application.save() # application is fix and send via django.core.mail EmailMessage self.send_mail(application) return True now when I had a good connection everything will work fine. But when it does not it will save the application but will not send the email. Resend is not an option since its a one time send supposedly. Now my idea to rollback the application and throw exception something like "Action Failed. Maybe poor connection. Please try again". try: application.save() self.send_mail(application) except ConnectionError?: # rollback ? raise Exception(msg) ? Any help and better way to handle it? Thanks for the help and sorry for the trouble. -
telethon - message to some channels does not forwarded

My problem is that for two of my channels forwarded messages are not sent to telegram server. In fact I get not any error and I see this on console msg forw to dest channel .... but it does not show on channel. This problem will show after some hours working and just for two of my channels (other channels work correctly).Now for solving the problem i restart Django app. It's interesting when I restart app, all sent messages that were didn't show in channel will come to channel.
